Diagnosis Coding:

Consult This Handy Reference For Correct OASIS, Code Dates

What do you do when your ‘From’ and M0090 dates split before and after Oct. 1?

Don’t waste resources and money by using the incorrect code set or OASIS. Use this quick list to determine the correct tools:

• If your M0090 and “From” date are before Oct. 1, use ICD-9 on RAP; ICD-10 on final claim

• For a “From” date in September but M0090 date in October use ICD-10 on OASIS-C1/ICD-10, ICD-9 on RAP, and ICD-10 on final claim.

• For a M0090 date in September but “From” date in October use ICD-9 on the OASIS-C1/ICD-9; and ICD-10 on the RAP and claim.
